I've lived and worked for a year in the UK, received salary and paid taxes there, but I returned to my home country.
I'm about to receive money for a work I've conducted for a foreign entity who'll wire money for me as payment from a UK account. (I haven't worked as an employee for them; I'll receive an advance on future royalties and if everything goes well more royalties.)
Is there a threshold under which I can receive such payments to my UK bank account without worrying about accidental tax avoidance?
Anything to watch out for?
